How to access canvas context in React and JavaScript?

To access canvas context in React and JavaScript, we can assign a ref to the canvas and call getContext on the ref’s value.

For instance, we write:

import React from "react";

export default function App() {
  const ref = React.useRef();
  console.log(ref.current.getContext("2d"));

  return (
    <>
      <canvas ref={ref} />
    </>
  );
}

to call useRef to create a ref.

Then we get the context by calling ref.current.getContext with '2d' to get the context.

Conclusion
